The boroughs that are set to receive the energy-saving grants are Barking Town Centre, Muswell Hill, Archway, Brixton, Lewisham Town Centre, Wandle Valley, Ham and Petersham, Peckham, Hackbridge and Queen's Park.
Commenting on the scheme, Mr Johnson said: "I am delighted to unveil the top carbon-busting neighbourhoods in London.
"There was a high calibre of bids from across the boroughs and it was a difficult choice, but the winning entries are championing the latest technologies, which will help us to become a leading low carbon city."
According to the Energy Saving Trust, people can slash their bills by as much as £60 a year if they switch off their tumble driers.
